HENRY S. FERGUSON, OF OKMULGEE, OKLAHOMA.

SLIDINGr-DOOR LOCK.

Application filed January 29, 1916.

T all 'whom it may concern.'

Be it known that l, HENRY S. FERGUSON, a citizen of theUnited States, residing at Okmulgee, in the county of Okmulgee and State of Oklahoma, have invented new and useful Improvements in Sliding-DoorLocks, of which the following is a specification.

T his invention relates to improvements in sliding doei' locks and has particular application to a lock for sliding 'doors of freight cars and the like.

ln carrying out the present is my purpose to providea sliding door lock whereby the door may be effectively locked I in closed position and the lock sealed and wherein the locking bolt will be under the control of a magnetic key so that opening of the door, in the event of the unauthorized breaking of the seal, by a key other than Aa magnetic key will be prevented.

lt is also my purpose to provide a sliding door lock wherein the component parts will be so arranged and correlated as to reduce the possibility of derangement to a minimum y and enable access to be had to such parts for the purposes of cleaning and repairing.

With the above and other objects in view,

the invention consists in the construction,

combination and arrangement ofY parts herei inafter set forth in and falling within the scope of the claims.

ln the accompanying drawings; Figure 1 is a view in side elevation ofa lock constructed in accordance with the present inv Fig. 2 is a horizontal sectional view therethrough. Fig. 3 is a vertical sectional view through the same. Figs. 4, 5 and 6 are views o details of the invention.

Referring now to the drawings in detail,

1 designates a portion of a sliding door.v

Mounted upon the outer side of the door 1 adjacent to the front edge thereof 1s avertical block 2, while mounted upon the inner surface of the door adjacent to the front edge thereof and disposed immediately behind tlie block 2 is a block 3 and passed tirough alining openings in the blocks 2 and 3 and in the door 1 are securing bolts 4 acting to hold the blocks securely fastened to the door. The inner block 3 is formed with a transverse slot 5 disposed at a point between the ends of the block and passed through alining openings formed in the blocks 2 and 3 and the door is a rod 6 eX- tending through the slot 5 and having the Specification of Letters Patent.

outer end thereof provided with a handle 7 whereby the rod may be rotated.

3 designates a locking bolt having one end 9 is a lever 10 having one end fixed uponV y the bolt 8 and the other end formed with a hook 11. The lower edge of the bolt 8 at the outer end thereof is formed with a groove 12 that opens into the slot'9 and formed at thev juncture of the groove 12 with the slot 9v is av shoulder 13 disposed adjacentto the'hook 11 on the leverlO. The jainb of the door opening is formed with a recess 14 in alineinent with the bolt 8 and fastened within this recess 14 is a substan Y tially rectangular casing 15 having the front and rear ends open and secured tothe lower wall of the casing ,1.5 and disposed within such casing is a block 16 having the upper edge formed with a shoulder 17 adjacent to the front end of the block and with a shoulder 18 adjacent to the rear end of the block, while extending transversely of the casing 15v and secured to the opposite side walls thereof adjacent to the top wall is a pin 19 upon which is mounted for swinging movement a holding vlug 20. In the present instance, a vertical block 21'is fastened to the outer side .of the door j amb and is formed with an opening 22 alining with openings in the'door jamb and in the front wall of the casing 15 and passed through these aliningl ,openings is a-rod 23 having the inner end formed with a laterally projecting lug i 24 arrangedadjacent tothe shoulder 17 and disposed alongside of the block 16, while fastened to the outer end of the rod 23 is a handle 25.

` In practice, when the door is slid to closed position, the bolt 8 carrying the lever 10 passes through the casing 15, while the shoulder 13 drops over the shoulder 18 on the block 16 and the hook 11 on the lever 10 engages behind the shoulder 17 on the block 16 and the holding lug 20 engages the upper edge of the lever 10 to hold the latter against upward swinging movement under the action of the rod 6. Thus, the door is securely held the door j amb is formed with a keyhole 26 in juxtaposition to the holding lug 2O and a v magnetic key 27 is adapted to be inserted the lateral lug 2a engages the lower edge of the locking bolt 8 and swings the latter upwardly to disengage the shoulder 13 from the shoulder 18, thereby permitting the door to be slid to open position.

In the present instance, the outer surface of the vertical block 21 ata point above the rod 23 is formed with ya transverse slot 28 f and mounted within the slot 28 and capable of swingingmovement therein 1s a horizontal bar 29 having' one end formed with an inwardly projecting lug` 30 adapted to overlap the keyhole 26, and the remaining end designed to enter the recess 3l formed in the block 2on the outer side of the door 1 and Formed in thev pivoted within said recess. outer surface of the strip 29 is a vertical slot 32 designed vto aline with a similar slot 33 formed in the handle 25 on the outer end of the rod 123. Passed through alining openings in the block 21 and the door j amb above the strip 29 and suitably secured in such openings is a rod 34 having the outer end formedlwith a lug 35. This lug 35 is pro- `vided with .a slot 36 that Vvalines with the slots 32 and 33 and slidably mounted within the slot 36 isa sealing pin 37 formed with a longitudinally extending slot 38 that receives a pin 39 extending across the slot 36 in the lug 35, the pin and slot 39 and 38 coacting to prevent detachment of the sealing pin from the lug After the door is locked in closed position, as previously described., thebar 29 is swung within thek slot 28 to engage one endthereof in the recess 31'and move the lug 30 over the keyhole and in this position of the strip, the vertical slot in the outer surface'thereof alines with the slots in the lug l35 and the handle 25 so that the sealing pin 37 may be passed through such alining slots and a seal applied to the lower end thereof to seal the door in locked position.

lfVhile I have herein shown and described the preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.

vI claim:

1. In a sliding` door lock, a bolt mounted upon the door and projecting over one edge thereof and formed with a longitudinally extending slot, a lever pivoted within said slot and formed with a hook, keepers carried by the door amb and adapted to be engaged' by said bolt and hooked lever respectively, and means formoving said bolt and lever out of engagement with the respective keepers.

2. In a sliding door lock, a bolt mounted upon the door and projecting over one edge thereof and formed with a .longitudinally extending slot, a lever pi'voted within said slot and formed with a hook, keepers carried by thedoor jamb and adapted to be engaged by said bolt and hooked lever respectively, means for moving said bolt` and lever out of engagement with the respective keepers, and means for sealing the door in closed position succeeding the locking thereof.

In testimony whereof I affix my signature in presence of two witnesses. HENRY S. FERGUSON:
